The value structure of Roderic O'Conor is mid-key: quiet, controlled, and cohesive. Roderic O'Conor builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #9AA65E delivers the chromatic peak at only 4.4% - a small shot of colour with outsized visual impact. At 66 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 5 sits within the larger chromatic argument that Roderic O'Conor's complete body of work advances.
